What is the purpose of infrared sensors?

Here are the uses of infrared sensors: 1. Perceive certain characteristics of the surrounding environment; 2. Measure the heat emitted by objects and detect motion: For example, cars and televisions use infrared detectors to interpret signals sent from remote controls. Below is the classification of infrared sensors based on operation: 1. Thermal type: Converts part of infrared rays into heat, extracting output signals such as resistance changes and electromotive force through heat. 2. Quantum type: Utilizes the photoelectric effect of semiconductor migration to absorb energy differences and the quantum type that employs the photovoltaic effect of PN junctions.

How Many Degrees Can the Steering Wheel Turn When Driving Straight?

When driving straight, the steering wheel should not turn more than 5 degrees. If the car body is not tilted, try not to move the steering wheel. Before entering straight driving, the steering wheel must be in a straight position, and the car should be aligned straight, so that during straight driving, there is no need for large movements of the steering wheel. If the steering wheel is not straight before entering straight driving, the direction should be corrected as soon as possible. During straight driving, just ensure the steering wheel is controlled properly to avoid crossing the edge lines. Common methods for straight driving: Looking far ahead while driving straight makes it easier to drive straight and judge whether the car body is deviating, helping the driver correct in time. To determine if the car is driving straight, you can also observe the distance between a certain part of the car body and reference objects like lane lines or fences with peripheral vision. Correct steering wheel operation method: Place both hands with appropriate force at the nine o'clock and three o'clock positions on the steering wheel, with fingers naturally gripping it and thumbs naturally extended along the edge of the steering wheel. Steering wheel techniques: On straight roads, use the 'correction method' to control the steering wheel. The correction method involves minor adjustments, only making slight corrections when the direction deviates from the center line. Each adjustment should be within 30 degrees to ensure smooth driving. For gentle turns, turn early and slowly, and return early and slowly. For sharp turns, turn late and quickly, and return early and quickly. Have predictive ability and prepare your hands before the turn begins.
